Xorcom's echo cancellation module provides a high level of echo cancellation and voice enhancement while reducing load on the CPU.
We are now shipping a hardware echo canceller module for Astribank telephony interfaces and the full line of Xorcom Asterisk-based IP-PBX appliances. This module provides a high level of echo cancellation and voice enhancement while reducing load on the CPU as compared to OSLEC, the software-based echo cancellation solution provided in the standard Asterisk framework.
Says Izzy Gal, VP Innovation at Xorcom:
By reducing the load on the server’s CPU, the number of simultaneous calls that are supported on the telephony system is increased significantly. We’ve set the echo tail size to 128 taps and our published load tests show that we achieve the same number of simultaneous calls as when we disable the software echo cancellation completely.
